V07E275PL4B5 application field and working principle

TVS (Transient Voltage Suppressors) are an important component in the protection of electrical systems and circuits against transient over-voltage. Varistors, also known as voltage-dependent resistors (VDRs), are the transient voltage surge suppressors, MOVs (Metal-Oxide Varistors). In combination, these components form the basis of reliable and efficient surge protection.

The V07E275PL4B5 model is part of the TVS-MOV family and is one of the robust and reliable solutions for protection of commercial, industrial and residential applications. This model is a multi-layered protection device featuring high surge capacity and advanced stabilizing features. This component is designed to protect against transient overvoltage and is suitable for connection in AC/DC power circuits with 500 Watts of peak surge and 18V DC working voltage.

The V07E275PL4B5 application field includes public lighting, security systems, transmitter lines, telecom equipment, air-conditioning systems, industrial machinery, and other sensitive electronic equipment that requires protection from sudden transient over-voltage. The design of this robust protection device also offers additional advantages such as complete insulation from the AC network frequency, robust surge holding capability and fast response time.

The robust design of the V07E275PL4B5 features two independent protection stages. The first stage provides a protective layer against transient over-voltage by clamping the voltage to a maximum value. This clamping action is triggered by sensing the over-voltage and triggering a current flow which in turn reduces the energy of the over-voltage pulse. The second stage features a resettable thermal fuse which cuts off the current path when a certain thermal threshold is exceeded, thus providing additional protection in situations of excessive current flow.

In addition to the voltage protection and stabilizing mechanism, the V07E275PL4B5 further offers robust hardware design features such as tough aluminum case for optimal heat dissipation, gold interconnects for reliable electrical connectivity, and heavy-duty contacts for secure connection to the power source. These features make the V07E275PL4B5 an ideal solution for long-term protection of sensitive equipment against voltage surges.

The V07E275PL4B5 is an advanced surge protection device designed to provide reliable protection against transient over-voltage. With two built-in protection stages, this model offers superior protection for a wide range of commercial, industrial and residential applications. The robust hardware design ensures a reliable connection to the power source and provides optimal heat dissipation for long-term protection.
